摘要

3 种不同的环境下，分别进行了两种不同纤维（T700/ZT7H）制备的单搭接接头的拉伸剪切性能试验，研究了不同环境对 J299 胶膜胶接接头剪切强度的影响。试验结果表明：T700 和 ZT7H 胶接接头在 ETW（高温湿态）环境下的剪切强度均值约为 RTD（常温干态）环境的 78% 和 79%，在 CTD（低温干态）环境下的剪切强度均值约为 RTD 环境的 1.11 倍和 1.04 倍。在 RTD、CTD 和 ETW 的环境下，ZT7H 胶接接头剪切强度分别是 T700 胶接接头强度的 1.32 倍、1.23 倍和 1.34 倍。

Abstract

The tensile shear experiments of two types of single-lap composite joints processed respectively by T700 and ZT7H fibers under three different environments are carried out to investigate the influence of different environments on shear strength of adhesive joints with J299 film. The experimental results proved that: The shear strengths of T700 and ZT7H adhesive joints in Elevated Temperature Wet (ETW) environment are respectively about 78% and 79% of that in Room Temperature Dry (RTD) environment

and the shear strengths in Cold Temperature Dry (CTD) environment are about 1.11 times and 1.04 times of that in RTD environment. Moreover

in RTD

CTD and ETW environments

the shear strength of ZT7H adhesive joints is 1.32 times

1.23 times and 1.34 times of that of T700 adhesive joints.
